Vehicle Theft Security System: Notes

WARNING: This page is about a different car, the 2002 Dodge Stratus and 2002 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

Vehicle Theft Security System (VTSS) monitors vehicle doors, hood, trunk key cylinder and ignition for unauthorized operation/entry. When VTSS is armed, operation of integrated garage door opener is disabled. When alarm is triggered, horn will sound for 3 minutes and parking lights will flash for 15-18 minutes.

When an unauthorized entry into vehicle occurs, Body Control Module (BCM) signals Powertrain Control Module (PCM) via the PCI bus that it is not okay to start engine. PCM then "zeros out" pulse width of fuel injectors, thus preventing engine from starting (start/stall condition). Engine will not start until VTSS is disarmed.
